IMPROVEMENT IN REGULATRS FOR GOVERNORS TO STEAM-ENGINES.

Specification forming part of Letters Patent No. 145,670, dated March 17, 1874; application filed January 10, 1874.

To all whom it may concern:

Be it known that we, WILLIAM L. B. CoL- LINs and J OsHUA DONALDSON, of Vacaville, county of Solano and State of California, have invented an Improved Regulator for Governors of Steam-Engines 5 and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings andletters marked thereon.

Our invention relates to certain improvements in governors; and it consists, principally, in a novel construction whereby we are at all times enabled to regulate the valve-spindle and move it up and down without stopping the governor, and thus open or close the valve more or less. Y

This is effected by means of a sort of double nut, which moves up and down upon a screw which unites the valve-spindle with the governor-stem.

This nut can be turned so as to bring the two stems nearer together or separate them more, as may be desired.

Referring to the accompanying drawings for a more complete explanation of our invention, Figure lis a side elevation of our governor. Fig. 2 is a section, showing the nut and screw uniting the two stems.

In the present case we have only shown a sufficient portion of the governor to illustrate the invention, and have omitted the drivinggears and the weights or balls, as these are,

common to all governors.

A is the frame of our governor, the baseplate B of which may serve as a cover or top to the valve-chamber. 'Ihe spindle C passes up through this cover and the stuffing-box G, and its upper end is secured to the bottom of a hollow screw, D, as shown. The governor-.

pin, c', projects from its lower end through the' slotf, which is made 'at one side of the screwand extends from the top to near the bottom, so that the pin can move up and down in the slot. A double nut, H, is fitted to the screw D, and the two haleswofwthis nut are placed one above ZnIIO-n'e below the pint, which iits in a groove cut in the two parts, so'that when the nut is turned around the pin will hold it in they/sargey relative position to the governorstem E( and the screw D will thus be forced toiove up or down along the stem E. By this means it will carry with it the spindle C, and thus raise or depress the valve, so that when thegovernor is running it will notbe necessary to stop it at any time for the purpose of regulating or changing the speed ot' the engine.

'Having thus described our invention, what we claim, and desire to secure by Let-ters Pat- The screw D, slotted as shown, and provided with the nut H, in combination with the governor-stem E, with the pin c', for the purpose of adjusting the valve stem C without stopping the engine, substantially as herein described.

In witness whereof we have hereunto set our hands and seals.
